To collect a lot of leads you better insert your newsletter signup form on every posts. But doing so it can be time expensive. With this addon you can automatically insert your forms at the end or in the middle of your posts and set exclusions by categories or tags.
So everytime you made an update to your form you will not waste time to update tons of posts.
You can also set different form for different posts, based on categories or tags. So you can register your leads to exact list on Mailchimp (see also our Mailchimp addon).
